Me; tangent lines find the value of x! explain! brainliest given!

6.6

Step-by-step explanation:

Since it is a tangent line, then the angle between x and 15.5 is a right angle. Therefore, you can use the Pythagorean Theorem:

leg² + other leg² = hypotenuse²

(x)² +    (13.5)²     = (x + 8.45)²

 x² +    182.25    = x² + 16.9x + 71.4025

           182.25    =        16.9x + 71.4025

           110.8475 =        16.9x

                    6.6 =              x

correct answer:

a + bi
